PURPOSE OF REVIEW A variety of techniques exist for secondary intraocular lens (IOL) implantation. Of note, scleral fixated intraocular lenses have become more popular with a variety of techniques, both with and without use of sutures. Herein, we focus on reviewing recently published studies describing the long-term outcomes of scleral fixation techniques. RECENT FINDINGS Although initial papers describing novel techniques often report short-term outcomes, several studies have recently described intermediate and long-term outcomes for scleral fixated IOLs, albeit all being retrospective case series. Suture fixation methods with long-term follow-up, up to a minimum of 50 months, report dislocation rates between 0 and 15%. Sutureless scleral fixation techniques have increased in popularity the past several years. Although they appear to have a lower rate of IOL dislocation several studies have reported 0% and one study 8%. The follow-up period for sutureless scleral fixation technique studies, however, is shorter with most studies reporting follow-up of less than a year. Rates of retinal detachment vary between individual studies, but are similar for both suture fixation and sutureless with the majority of studies reporting a rate between 0 and 5%. These studies show that long-term outcomes are important considerations in surgical decision-making. SUMMARY Scleral fixation techniques have shown long-term durability and safety in recent retrospective studies. Comparison of techniques has been limited, and more robust studies may be required to provide stronger anatomic, functional, and comparative data.BACKGROUND Immunocompromised children are at increased risk for respiratory syncytial virus (RSV) infection with associated morbidity and mortality. Prophylaxis is usually provided to these children on a case-by-case basis. METHODS Immunocompromised children who received ?1 injection of palivizumab were prospectively enrolled across 32 Canadian sites, between 2005 and 2017, during the RSV season. We assessed respiratory illness hospitalization (RIH) and RSV-related hospitalization (RSVH) hazard ratios (HRs) in immunocompromised children versus infants' prophylaxed for standard indications (SI prematurity ?35 weeks' gestation, bronchopulmonary dysplasia, and congenital heart disease) and complex medical disorders (CMD). Data were analyzed using t-tests, χ and Cox proportional hazards adjusted for confounders. RESULTS A total of 25,003 infants were recruited; 214 immunocompromised, 4283 CMD, 20,506 SI. On average, children received 4.4 ± 1.3 injections. A total of 16,231 children were perfectly adherent (58.4% immunodeficiency, 68.9% CMD, 64.2% SI; P less then 0.0005). A higher proportion of immunocompromised children were aboriginal and exposed to smoking compared with CMD and SI. Immunocompromised children also had a higher median; gestational and enrollment age and birth weight compared to CMD and SI. Immunodeficient children had a higher RIH risk compared with SI (HR = 2.4, 95% confidence interval, 1.3-4.7, P = 0.009) but were similar to CMD (HR = 1.7, 95% confidence interval, 0.9-3.4, P = 0.118). RSVH in prophylaxed, immunocompromised children was similar to CMD (HR less then 0.005, P = 0.955) and SI (HR less then 0.005, P = 0.953). CONCLUSIONS Immunocompromised children who received palivizumab had an increased RIH hazard compared to the SI group. Similar RSVH hazard between the 3 groups suggests that immunocompromised children may benefit from palivizumab during the RSV season.BACKGROUND High doses of ampicillin are often used to achieve therapeutic drug concentrations in infants. A paradoxical antibiotic effect, often called the Eagle effect, occurs when increasing concentrations of antibiotic above a threshold results in decreased efficacy. It is unknown if infants treated with ampicillin are at risk for this paradoxical effect. METHODS We identified infants MIC ?50% decreased both duration of bacteremia and odds of prolonged bacteremia.BACKGROUND Infection is one of the most common complications of ventriculoperitoneal (VP) shunts. Its optimal management is controversial. We aimed to report current practice within a large pediatric neurosurgical center. METHODS We retrospectively studied a cohort of children less then 15 years with VP shunt infection, who underwent treatment from March 2011 to March 2018 in the main referral children hospital in Isfahan, Iran. Patients with distal shunt infection or associated wound infection were not included. The initial protocol was empiric intravenous antibiotic therapy and repeated evaluation of cerebrospinal fluid (CSF) analysis and culture. After obtaining the culture results, antibiotic regimen was adjusted according to the sensitivity results. Response to protocol was defined as negative culture results after 72 hours of appropriate antibiotic, which persisted at least for 1 month after discontinuation of therapy. In patients who failed to respond to protocol, the shunts were replaced. RESULTS Totally, 148 cases with mean (SD) age of 21.2 (30.1) months included to the study. Of which, 56.1% were boys and 68.2% had responded to the protocol. This response was significantly prominent in patients who infected with Gram-negative bacteria (82.9%), especially with Acinetobacter spp. (100%) and Pseudomonas aeruginosa (100%). The response was significantly higher in patients with CSF glucose of greater than 40 mg/dl (83% versus 58.1%, respectively, P = 0.004). CONCLUSION We found that using only intravenous antibiotics is sufficiently enough for treating many children with VP shunt infections, especially in those infected by Gram-negative organisms and CSF glucose level of greater than 40 mg/dl.BACKGROUND Patients with heterotaxy syndrome (HS), commonly associated with hyposplenism and complex congenital heart disease (CCHD), require multiple-stage single ventricle type operation for long-term survival. Although a higher risk of community-acquired sepsis and mortality rate was reported in CCHD with HS compared to those without HS, whether the risk of postoperative severe bacterial infection (SBI) is higher in patients with HS remains unknown. https://www.selleckchem.com/products/pf-06882961.html METHOD All patients with CCHD (with and without HS) born between 2001 and 2013 who received cardiac surgery between 2001 and 2018 were enrolled. We analyzed the epidemiology and risk of postoperative SBI in this CCHD cohort. RESULT In total, 101 patients of CCHD with HS and 164 patients without HS were enrolled. The mean postoperative nosocomial SBI rate was 0.73/100 patient-days in patients with HS and 0.56/100 patient-days in patients without HS (P = 0.13). Multivariate Cox regression analysis demonstrated that the most critical risk factor for postoperative SBI was postoperative intubation &gt;14 days.
